3 Claims. (Cl. 137-267) This invention relates to a valve and moreparticularly to a twin body valve particularly designed for use withrespect to tank trucks commonly used in the petroleum industry for thedelivery of what are known as white products and brown products. Suchtank trucks are commonly built with a plurality of compartments. It iscommon practice to deliver an entire truckload'of either white or brownproducts. White products include gasoline while brown products includediesel fuel, kerosene etc. Mixing or contamination of the two productsmust be avoided or reduced to a minimum. It is also common practice toload a tank truck with two compartments of white products and twocompartments of brown products.

It has been determined that a meter for such products which has beencalibrated and sealed for the delivery of a white product will notaccurately measure the delivery of a brown product and vice versa.Accordingly, it is desirable to provide means upon the variouscompartments of a tank truck by which its contents may be diverted toone meter for white products and to another meter for brown products. Itis also desirable that any contamination or commingling of the twoproducts be avoided or reduced to a minimum.

It is accordingly one object of the present invention to provide a valvefor the above-mentioned use.

It is a further object of this invention to provide such a valve bywhich the contents of a compartment can be selectively diverted toeither of two meters.

It is a further object of this invention to provide a valve of the typedescribed wherein the bodies of the valve are so positioned as tocompletely drain not only the tank being drained but the valve itself soas to prevent contamination of the product when the tank is later usedfor the transportation of a diiierent product.

It is a further object of this invention to provide means for makingadjustments to compensate for misalignment of valves attached toseparate tank compartments when connecting piping between such valves toprovide a straight-through passage.

It is a further object of this invention to provide such a valve havingmeans associated with each diverting valve for connecting the variouscompartments in series for a straight-through passage of all of theliquids contained therein.

These and other objects, features and advantages of the presentinvention will be readily apparent from the annexed specification, inwhich:

Figure l is a top view of a valve embodying the present invention.

Figure 2 is a section taken along the line 2-2 of Figure l.

Figure 3 is a section taken along the line 3-3 of Figure 2.

Figure 4 is an enlarged fragmentary section taken along the line 4 4 ofFigure 2.

Figure 5 is an elevation of a tank truck showing the rates Patent "iceconnection of a series of valves attached to the several compartmentstherein.

Figure 6 is a top plan view of Figure 5.

Referring now more particularly to the drawings, the valve isillustrated as comprising a body 10 including a pair of chambers 11 and12 disposed at an angle as indicated. Between the two chambers 11 and 12there is a chamber A having a V-shaped cross section as shown, at theedges of which there is provided a flange 13 providing bolt holes 14 andan inlet port 15. The flange 13 and bolt holes 14 provide means forattaching the valve to the underside of a tank with the port 15registering with the opening in the bottom of the tank. Each of thechambers 11 and 12 is similar and each is provided with a wall 16provided with a tlange 17 which is tapped to receive the studs 18 bymeans of which the ilange 19 with a cap 26 is bolted thereto. Each ofthe chambers 11 and 12 is provided with an inwardly turned ange 21 whichprovides a circular opening 22 into the V-shaped chamber A and providesa valve seat 23. A plurality of centering lugs 24 are positionedadjacent the edge of the opening 22.

The wall 16 is provided with opposed ports 25 and 26 machined to aspherical inner surface to receive spherical ball iittings formed on theoutside of piping, which piping is retained by iianges also machined toa spherical inner surface and attached to the valve body. Ring seals 27are provided to prevent leakage. A valve stem 28 extends through eachcap 20 and is threadedly received therein in the conventional manner,which valve stem carries at its inner end a nut 29 by means of which aplate 3d clamps a rubber gasket 31 and a rubber sealing ring 32 to aplate 33. The plate 33 is seated against the shoulder 34 formed by areduced portion of the valve stem 28 and is provided with an annulargroove 35 for receipt of the ring 32 and with an annular boss 36 forpositioning a coil spring 37 which is provided having one end bearingagainst the plate 33 and the other end bearing against the inner end ofthe cap 20. As most clearly indicated in Figure 4, the rings 32 seatagainst the valve seat 23 when the valve is closed, being centeredthereto by the centering lugs 24.

Figs. 5 and 6 illustrate the application of the abovedescribed valvewith the outlets 39 in the bottoms of the several compartments 40, of atank 41 of a tank truck 42, the compartments being defined by partitions43 and end walls 44. The valves 10 may be attached to the bottoms of theseveral compartments by aligning the nlet port 15 of a valve with theoutlet 39 in the tank and bolting the liange 13 to the area of the tanksurrounding the outlet 39. Piping, comprising two parallel lines 45 and46, interconnect the aligned wall ports 25 and 26 of the several valves,the pipe sections forming the lines having end llanges adapted forattachment with ilanges on the wall 16 surrounding the ports 25 and 26.The rear ends of the pipe lines 45 and 46 may include conventionalmeters and screw threaded, valve controlled, discharges for connectionwith a flexible hose.

It will be noted that the chambers 11 and 12 are disposed at an angle.Assuming the valve above-described to have been attached to a tank truckby bolting the iiange 13 over the opening in the bottom of the truck andsuitable piping valves and meters to be attached to the openings 25 and26, as described above, it will be apparent that by opening the valvecontained in the chamber 11 while the valve contained in the chamber 12is left closed, liquid in the tank truck will be drained through thechamber 11 and to the desired meter. Likewise, if the valve contained inthe chamber 11 is closed and the valve contained in chamber 12 is open,the product contained in the tank truck may be diverted to a differentmeter. In order to avoid the necessity of a plurality of meters of thesame type where a number of compartments of the truck are to be used tocarry the same product, there is provided the two discharge openings 25and 26 in each of the chambers 11 and 12. In this manner, all of thecompartments containing the same product may be connected in series tobe passed to the appropriate meter. It will also be apparent that aseach of the chambers 11 and 12 is disposed at an angle, the iluidcontained therein will be drained and any uid contained in the chamber Awill be drained out through whichever of the valves is open so that uponrefilling of the tank truck compartment with a dlterent product,contamination is avoided or reduced to a minimum.

While there has been described what is at present considered thepreferred embodiment of the invention, it will be understood thatvarious changes and alterations may be made therein without departingfrom the essence of the invention and it is intended to cover herein allsuch changes and alterations as come within the true scope and spirit ofthe annexed claims.
